Carboxylic Acid Fungicides: Benefits and Resistance Management

26 February 2025, New Delhi: Introduction to Carboxylic Acid Fungicides

Carboxylic acid fungicides, such as oxolinic acid, play a vital role in managing fungal and bacterial diseases in crops. These fungicides target key metabolic pathways in pathogens, inhibiting their growth and reproduction. Although carboxylic acid fungicides are effective, they also come with a risk: the potential for resistance development.

Resistance Challenges in Fungal Pathogens

Resistance to carboxylic acid fungicides has already been documented in some fungal species, with pathogens becoming less responsive to treatment over time. Understanding the nature of this resistance and how it develops is crucial for effective fungicide management. Though resistance risks in fungi are not yet fully understood, it remains a high priority for agricultural professionals to manage these chemicals carefully.

Best Practices for Resistance Management

To manage the resistance risks associated with carboxylic acid fungicides, farmers must follow the resistance management strategies outlined by FRAC. This includes using fungicides as part of a broader integrated pest management (IPM) approach. Rotating fungicides with different modes of action, ensuring proper application rates, and combining chemical treatments with cultural practices are all essential components of effective resistance management.
